These weight-s vary slightly for different fruits, and in commercial packing the fill 

 is not quite as strong as in these experiments. The figures, however, will furnish a 

 fairly close guide as to the quantity of sugar required in canning. They also point 

 to a cause of some of the difficulties in correct labeling under the new net-weight law.
